Virtual 3D Technology
Reproducing a Dolby Digital or Dolby Pro Logic source requires the use of a total of 4-6 speakers placed before and
behind the listener, using a substantial amount of space that may not always be available.
The RP-U100 features Yamaha's unique "virtual 3D" technology for generating virtual surround using just two speakers.
Even with only two front speakers, this technology produces a sensation of "virtual rear speakers" and provides a
pleasant sense of width and motion of sound behind you.
You can also take advantage of this RP-U100 application to create virtual 3D parameters to match your personal taste.
